Making some change to specification before release…<\/p>\n\n\n\n

Disclaimer <\/h2>\n\n\n\n

Products are developed from extension of my hobby, and little amount is hand-made and sold for other hobbyists.<\/p>\n\n\n\n

Since they are hand-made by me, there may be initial failure, poor quality in soldering, lack of quality in design, etc. Recommended to use for hobby purpose<\/p>\n\n\n\n

Please read and understand specification of this product, and test before using. I will hold no responsibility for any damage or harm caused by the use of this product.<\/p>\n\n\n\n

Description<\/h2>\n\n\n\n

Useful tool based on ESP32 for developing ATMega328 microcomputer such as Arduino UNO, Nano. Have following features.<\/p>\n\n\n\n

  • Write \/ fix Bootloader<\/li>
  • Fuse
    • Check setting<\/li>
    • Set fuse (bootloader enable\/disable, read only, clear)<\/li><\/ul><\/li>
    • Arduino as ISP (avrdude via USB)<\/li>
    • avrdude via WiFi<\/li>
    • Burn hex file (compiled sketch\/bootloader) stored in microSD<\/li>
    • EEPROM
      • Read and view (HEX \/ ASCII format)<\/li>
      • Save data to microSD<\/li>
      • Clear<\/li>
      • Write EEPROM data saved to microSD<\/li>
      • View EEPROM data saved to microSD<\/li><\/ul><\/li>
      • Serial monitor
        • View text<\/li>
        • View simple graph<\/li>
        • Save data to microSD<\/li><\/ul><\/li>
        • View text file stored in microSD<\/li>
        • WiFi
          • AP \/ STA mode, off<\/li>
          • Sync with NTP server (file timestamp)<\/li>
          • Configure WiFi connection from smartphone<\/li><\/ul><\/li>
          • HTTP server (Access from PC \/ phone browser)
            • File list in microSD<\/li>
            • Download file in microSD<\/li>
            • Upload file to microSD<\/li>
            • Delete file from microSD<\/li><\/ul><\/li><\/ul>\n\n\n\n

              Many useful functions such as configure or write bootloader, burn hex file saved in microSD, check data in EEPROM, serial monitor debugging.<\/p>\n\n\n\n

              Files can be transferred to \/ from microSD via WiFi using smartphone, so for example, you can fetch EEPROM data from chip to microSD, then transfer to smartphone, attach to mail and send (AP mode will connect tool and smartphone directly).<\/p>\n\n\n\n

              Power can be supplied from USB connector on tool, or can be supplied from target board.<\/p>\n\n\n\n

              Other usage can be considered, such as modify tool program source (preparing) to view serial monitor or EEPROM data in customized format, change value every time writing to EEPROM for assigning unique ID per chip. <\/p>\n\n\n\n
